Introduction: Placenta accreta spectrum disorders are among the leading causes of maternal morbidity and mortality and their prevalence is likely to increase in the future. The risk of placenta accreta spectrum disorders is highest in cases of placenta previa overlying a previous cesarean section scar. Few studies have evaluated placenta accreta spectrum disorders in Portugal. The aim of this study was to review the cases of placenta accreta spectrum overlying a cesarean section scar managed in a Portuguese tertiary center over the last decade.Material and Methods: Retrospective, cross-sectional study, with data collected from hospital databases. Only cases with histopathological confirmation of placenta accreta spectrum were included.Results: During the study period, 15 cases of placenta accreta spectrum overlying a cesarean section scar were diagnosed (prevalence 0.6/1000). All cases were diagnosed antenatally. A transverse cesarean section was present in all cases; 13 were managed by a scheduled multidisciplinary approach, while two required emergent management. Total or subtotal hysterectomy was performed in 12 cases. There were no cases of maternal or neonatal death. Histopathological evaluation confirmed nine cases of placenta accreta, three cases of placenta increta and three cases of placenta percreta.Discussion: Early antenatal diagnosis is important for a programmed multidisciplinary management of these cases, which may reduce potential morbidity and mortality and ensure better obstetric outcomes.Conclusion: This case series of placenta accreta spectrum overlying a cesarean section scar reports the reality of a tertiary-care perinatal center in Portugal, in which no maternal or neonatal mortality due to placenta accreta spectrum was registered over the last decade; this may be attributed to prenatal diagnosis and a coordinated multidisciplinary team approach.

Abstract Background The incidence of PAS disorders increased rapidly in recent years, and introvoxel incoherent motion (IVIM) MRI has been applied in the assessment of placenta. The study aims to investigate whether the parameters from IVIM can be used to differentiate patients with PAS disorders complicating placenta previa and secondly to differentiate different categories of PAS disorders. Methods The study participants were comprised of 99 patients with placenta previa, including 16 patients with placenta accreta, 51 patients with increta, 8 patients with percreta and 24 patients without PAS disorders between 28 + 0 and 39 + 6 weeks. IVIM MRI was performed on a 1.5 T scanner. Perfusion fraction (f), pseudodiffusion coefficient (D*) and diffusion coefficient (D) were calculated. Results Women with PAS disorders had a higher perfusion fraction (p = 0.019) than women without the disease. Multiple comparisons showed perfusion fraction in patients without PAS disorders was significantly lower than in patients with placenta accreta and percreta(P = 0.018 and 0.033 respectively), but was not lower than in patients with increta(p = 1). Conclusion Patients with placenta accreta and percreta differed in placental perfusion fraction from women with increta and without PAS disorders.

The Mean

Indications for the use of transarterial embolization (TAE) for postpartum hemorrhage (PPH) have been established. However, the efficacy of TAE for PPH complicated by disseminated intravascular coagulation (DIC) remains controversial. In this study, we investigated the efficacy of TAE for PPH complicated by DIC. A database review was conducted to identify patients who were treated with TAE for PPH at our hospital. TAE was performed in 41 patients during the study period. Effective hemostasis was achieved in all cases, but additional procedures, such as re-embolization or hysterectomy, were required in five patients (12.2%). The typical causes of PPH included uterine atony (18 cases), placenta previa (15 cases), amniotic fluid embolism (DIC-type) (11 cases), and placenta accreta spectrum (10 cases). The mean blood loss was 3836 mL. The mean obstetrical DIC and the International Society on Thrombosis and Hemostasis DIC scores were 7.9 and 2.6, respectively. The efficacy of hemostasis was comparable between patients with and without DIC. However, the complete success rate of TAE was lower in patients with DIC as the condition worsened than that in non-DIC patients. Overall, TAE is effective as a minimally invasive treatment for PPH complicated by DIC.

The definition placenta accreta spectrum disorders (PAS) introduced by FIGO (International Federation of Gynaecology and Obstetrics) indicates an abnormal, pathological adherence or invasion of the placenta. The growing worldwide incidence of this pathological entity, and the possible serious correlated surgical risks, has caused a significant increase in attention among the scientific community. Previous caesarean delivery and presence of placenta previa are the main risk factors for the onset of PAS. Here, we present the intriguing case of a 39-year-old woman, at the 33rd week of gestation, with six previous caesarean sections and with a diagnosis of placenta previa accreta. At our referral center for PAS disorders, we successfully managed this difficult case with the help of a multidisciplinary skilled team.

Abstract Objective The primary aim was to investigate whether the parameters from IVIM can be used to differentiate patients with PAS disorders complicating placenta previa. A second aim was to determine whether these parameters can be used to differentiate different categories of PAS disorders complicating placenta previa. Methods All the patients had placenta previa, including 16 patients with placenta accreta, 51 patients with increta, 8 patients with percreta and 24 patients without PAS disorders between 28+0 and 39+6 weeks. All women underwent MRI examination including an IVIM sequence at 1.5T scanner. The perfusion fraction(f), pseudodiffusion coefficient (D*) and standard diffusion coefficient(D) were calculated. Results Women with PAS disorders had a higher perfusion fraction (P<0.05) than women without the disease. Multiple comparisons showed perfusion fraction in patients without PAS disorders was significantly lower than in patients with placenta accreta and percreta(P<0.05), but was not lower than in patients with increta(p>0.05). Conclusion Patients with placenta accreta and percreta differ in placental perfusion fraction from women with increta and without PAS disorders. The perfusion fraction can be used as a reliable index to evaluate placenta perfusion fraction.
